To all whom it may .conocidal Be itknownthatl, EvANGELIsTE MAR- LEAU, of Houghton, in the county of Houghton and State of Michigan, have invented a newandImprovedFasteningDevice forI-Ioldback-Straps, of whichthe following is a full, clear, and exact description. v

My inventionrelates toa fastening device for hold back straps, and has for its object to to provide a device especially adapted to be employed as a substitute-for ,the leather loop -or staple securedV upon shafts,and the strap that is ordinarily Wound around. the shafts for the purpose of connecting the shafts with the hold back strap of a harness;

A further object of thje invention is to construct the device in ya simple, durable and economic manner, and in two adjustable sections, one of which is to be attached permanently to the shafts and the other to the holdback strap, and to provide a means whereby the two sections may be conveniently placed in locking engagement, or unlocked, even when the operator is Wearing mits or gloves. The invention consists in the novel con struction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure lis a plan view of the device. Fig. 2 is a longitudinal vertical section, taken essentially on the line 2-2 of Fig. 1; and Fig. 3 is a transverse section taken essentially on the line 3-3 of Fig. 2.

The device, as heretofore stated, is constructed in two sections, a body or shaft section A and a locking or strap section B. The

'shaft or body section A, consists of a block adapted to be secured by screws or other fastening devices upon the top of a shaft, the

lower surface of the block being rendered concave to fit the convexed surface of the shaft, as shown in Fig. 1, and the block is made substantially rectangular in cross section, and it may be made of any desired length, but in any event it is made considerably longer than it is Wide. The block is provided with a longitudinal sltl0, extending nearly from end to end, the slot being preferably inverted T-shape in cross section, as shown best in Fig-8; and upon the upper 55 surface of the block, at each side of the slot, teeth l1, are produced, inclined upon one face and straight upon the other, as shown best in Fig. 2. A

The locking or strap section B, consists of a plate 12, which plate is provided upon its under surface at each side of its center with teeth 13, longitudinally arranged,.the teeth being sunken in the saidA under surface ofthe plate, whereby a flange 14, is formed at each 6 5 side of the plate; and the plateupon its under surface is preferably reinforced at the center by a rib 15, capable of entering the upper portion of the body slot 10 and sliding therein, as shown in Fig. 3. 7o

- A button 16, or the equivalent thereof, is held to turn'upon the rib'l of the plate. The

shank of this button is carried upward through a suitable opening made vertically in the plate 12, in which opening the shank turns; but above the plate the shank is provided witha flattened face 16, which part is substantially rectangular in cross section, and is connected with a head 17, by means of which the button is turned. The button is held in' whateverfSo position it may be placed through the medium of a spring 18, which has constant bearing upon the flattened face 16au of the button shank, the spring being secured at its opposite end preferably to an odset produced upon the plate 12, and is constantly iexed to a greater or less extent by engagement with a pin 19, also secured in the plate.

A tongue 21, is horizontally projected froi the upper portion of oneend surface of the 9o plate, and this tongue is preferably semi-circular in edge contour; and in connection with the plate 12 a loop or link 22, is employed, adapted as a means of attachment to the hold back strap; and lthe said link or loopA is provided with a bifurcated shank receiving between its members the tongue 2l, and the two parts are pivotally connected through the medium of a pivot pin 23, or its equivalent.

As heretofore stated, the section B, is adapt` ed to be secured permanently to the hold-back strap, the strap being usually passed through the loop erlink 22. Thus the hold-back strap may be quickly brought into locking engagement with the-shafts by causing the rib of its plate 12 to enter the slot in the Vbody section of the device, and turning the button so that it will stand transversely within the wider portion of the slot, as illustrated in Fig. 3. The teeth upon the body portion, and the teeth in the strap section of the device are adapted for locking engagement and serve as an additional means for holding the two sections in close and locking relation. Y

It is evident that the device may be manipulated in a convenient and expeditiousmanner either to effect a locking engagement between the hold back strap and the shafts, or to release one from the other. The teeth also serve to' assist in adjusting one section upon the other, either forwardly or backwardly, according to whether the strap is too long or too short; and it will be understood that the device may be'made of any size or of any suitable material.

Having thus described my invention, I

claim as neW and desire to secure by Letters Patent- 1. Inafasteningdeviceforhold-backstraps, a toothed and longitudinally ,slotted section adapted to be secured to the shaft, a toothed engagement with the teeth of the body sec- 4o a longitudinally` slotted and toothed body section adapted for attachmenttothe shaft, a

locking section adapted for attachment to the hold back strap, provided with teeth for engagement with the teeth of the body section, and a spring-controlled button carriedby the locking sectionand adapted to enter and turn in the slot of the body section, substantially as shown and described.

4. In a fastening device forhold back straps, a longitudinally slotted and toothed b'ody section adapted forattachment to the' shaft, a

locking section'adapted fora'ttachment` to the hold back strap, said locking section comprising-a toothed plate, the teeth being adapted for engagement with the teeth of the body section, a spring controlled oblong button carried by the plateand adaptedY to enter and turn in the slot of the body section, and a link or loop having pivotal engagement with the plate, substantially as shown'and described.

5. A fastening device for hold back straps, comprising a' longitudinally slotted and toothed body section, a toothed locking section, a locking device carried by the locking section, and adapted to enter lthe slot of the body section and a link o rloop pivotally con,- nected with the locking section, substantially as and for the purpose set forth.
